I think this patch is mostly correct, but I think the change to
planner.c isn't quite right.  ordered_rel->reltarget is just a dummy
target list that produces nothing.  Instead, I think we should pass
path->pathtarget, representing the idea that whatever Gather Merge
produces as output is the same as what you put into it.

See attached.
